[TenTec] On the Corsair II revival idea and receiver noise

[GARY HUBER]

Old TenTec built the crystal ladder filters by bulk purchase of the 
basic crystals which were apparently sorted into lots of high, on, and 
low, (as indicated by color dots) groups for the filters. At any rate in 
house construction or bulk purchase of filters for a production run or 
sale later would NOT be at retail, one at a time pricing from Inrad.
